The kinetics of chlorophyll fluorescence were measured in Portulacaria afra (L.) Jacq. when the plants were functioning in either Crassulacean acid metabolism (CAM) or C(3)/CAM cycling (called cycling) modes, as determined by fluctuation in titratable acidity and gas exchange properties. Cycling plants showed primarily daytime CO(2) uptake typical of C(3) plants, but with a slight diurnal acid ...

This study aimed to evaluate the effects of seven stages (Lonicera caerulea berry juice, after enzymatic hydrolysis, sugar and acid adjustments, fermentation, deacidification, clarification ageing) in making Lonicera wine on anthocyanins antioxidant capacity were studied. The total anthocyanin content was determined by pH-differential method. composition measured HPLC-MS/MS. 1,1-diphenyl-2-picr...

Acid-catalyzed hydrolysis of glycosidic bonds is the most important degradation mechanism affecting cellulose-based materials. It results in decrease DP and loss original mechanical properties. The neutralization acidity therefore one efficient ways to hamper cellulosic artworks. However, case acidic strongly degraded artifacts, addition deacidification, a consolidation treatment must be perfor...

This work concerns non-pressure granulation of mineral materials used for the production agricultural fertilizers soil deacidification. In order to expand product range Nordkalk Poland sp. z o. located in Poland, conditions gypsum–lime mix were examined with use various methods. The processed mixture was Jurassic lime flour mined Sławno mine (Poland) and waste gypsum (sulfogypsum) obtained from...
